Wa alaikum assalam
Thank you for your kind words.
My best advice would be to continue studying the Quran as much as possible for yourself as I am sure you are doing. Then extract the wisdom from its narratives, particularly the stories in the Quran and present them with a view to teach your children according to their ages. This way, they will gain increasing familiarity with the Quran's guidance and you will have an opportunity to ponder deeper.
As you know, there are beautiful stories in the Quran. I would also be inclined to look for material designed for children that focus on narrating stories from the Quran primarily.
As your children get older, you can always give them a Quran with an easy translation for them to read for themselves. The idea is to get them to remain focused on the Quran's verses and for them to gain complete familiarity with them.
I believe that a parent should always teach a child 'how to think' as opposed to 'what to think'. It is the approach that is most important. That way children who will one day become adults Insha’Allah will always be able to think and 'discern' for themselves.
I hope that helps in some small way, Insha’Allah.
Kind regards,
Joseph
